DNA-based mutation analysis on the connexin 32 gene was performed in 49 families with Charcot-Marie-Tooth disease (CMT) type 1 but without duplication involving the chromosomal region, 17p12-p11.2. Mutations were identified in five of the 49 families, and four of the five mutations were hitherto und

โฆ Synopsis
Charcot-Marie-Tooth (CMT) disease consists of genetically heterogeneous neuropathies. Molecular genetic procedures have shown that most patients with CMT type 1 (autosomal dominant, hypertrophic form) have 1.5 Mb CMTlA duplication containing peripheral myelin protein-22 (PMP-22) gene

Connexin32 (Cx32) is a gap junction protein and its mutations are responsible for X-linked Charcot-Marie-Tooth disease. We examined the functional abnormality of C6 glioma cells transfected with mutant (C53S and P172R) Cx32 genes. Nontransfected C6 did not express Cx32. Northern and Western blot ana
